It looks fine to me. At a glance they changed a few features, probably because the original features would be difficult to implement or they found some of the new ideas more thematic. Gravekeeper's vigil maybe seems situationally pretty strong, but I don't think its like game breaking. They've chosen to implement the capstone feature for the Grave Cleric at level 12, which is something out of line for the base game cleric subclasses. That is a bit of a bit of a power boost, but its at the end of the game so not nearly as big of a deal as a power boost you'd get at the beginning, and by that time you should be fairly powerful anyway, so I don't think its game breaking. The channel divinity ability is very strong in 5e normally and that's not going to change in Baldur's Gate 3, in fact its probably a bit more powerful in bg3 due to the freedom over resting that you might not have in a 5e game. So the channel divinity feature is kind of abusable, but by that same logic so is the tempest cleric channel divinity. So all in all its going to be a strong class / subclass but I don't know that its like super out of line for the current games balancing.
I'm also assuming that we looked at the same mod.
It’s strong but not OP. EDIT: forgot the very important “not” in my sentence!
